Source of materials

5-Chlorosalicylaldehyde (1.56 g, 10 mmol), hydrazine hydrate (0.25 g, 5 mmol) and ethanol (30 mL) were heated and stirred at 353 K for 8 h. Then the solvent was concentrated and filtered. The crude product was recrystallized from ethanol to afford yellow crystals (1.31 g, yield 85%).

Experimental details

All hydrogen atoms were identified in difference Fourier syntheses. The U iso values of the hydrogen atoms of phenolic hydroxyl groups were set to 1.5U eq (C) and the U iso values of all other hydrogen atoms were set to 1.2U eq (C).

Comment

Schiff bases are a class of compounds containing the imino group –C=N–, which have important chemical and biological properties [4, 5]. Schiif bases may have antibacterial, anti-inflammatory, anti-tumor and anti-viral biological activities [6, 7]. Salicylaldehyde Schiff bases are an important class of chemical analysis reagents and organic ligands, and they are widely used in fluorescent probes [8]. We have also reported some Schiff bases of salicylaldehyde [9, 10].

The asymmetric unit of the title structure contains one half of the title molecule (see the figure). It can be clearly seen in the structure that the intra molecular hydrogen bonds are formed between the hydrogen atom of the phenolic hydroxyl group and the nitrogen atom of the imine. The molecule is in the trans configuration at the C(7)–N(1) double bond (1.273(3) Å). The bond angle of N(1)–C(7)–C(1) is 121.57(19)°. The geometric parameters of the title structure are all in the expected ranges [11].
